This patch tries to change hvc_console to not use request_irq/free_irq if
the backend does not use irqs. This allows virtio_console to use hvc_console
without having a linker reference to request_irq/free_irq.In addition, together with patch 2/3 it improves the performance for virtio
console input. (an earlier version of this patch was tested by Yajin on lguest)The irq specific code is moved to hvc_irq.c and selected by the drivers that
use irqs (System p, System i, XEN).I replaced "int irq" with the opaque "int data". The request_irq and
free_irq calls are replaced with notifier_add and notifier_del. I have also
changed the code a bit to call the notifier_add and notifier_del inside the
spinlock area as the callbacks are found via hp->ops.Changes since last version:
o remove ifdef
o reintroduce "irq_requested" as "notified"
o cleanups, sparse..I did not move the timer based polling into a separate polling scheme. I
played with several variants, but it seems we need to sleep/schedule in
a thread even for irq based consoles, as there are throttleing and buffer
size constraints.I also kept hvc_struct defined in hvc_console.h so that hvc_irq.c can access
the irq_requested element.Feedback is appreciated. virtio_console is currently the only available console
for kvm on s390. I plan to push this change as soon as all affected parties
agree on it. I would love to get test results from System p, Xen etc.Signed-off-by: Christian Borntraeger

With the coming of kernel based modesetting and the memory manager stuff,
the everything in one directory approach was getting very ugly and
starting to be unmanageable.This restructures the drm along the lines of other kernel components.
It creates a drivers/gpu/drm directory and moves the hw drivers into
subdirectores. It moves the includes into an include/drm, and
sets up the unifdef for the userspace headers we should be exporting.Signed-off-by: Dave Airlie

This includes code for new fifo-based xps_hwicap in addition to the
older opb_hwicap, which has a significantly different interface. The
common code between the two drivers is largely shared.Significant differences exists between this driver and what is
supported in the EDK drivers. In particular, most of the
architecture-specific code for reconfiguring individual FPGA resources
has been removed. This functionality is likely better provided in a
user-space support library. In addition, read and write access is
supported. In addition, although the xps_hwicap cores support
interrupt-driver mode, this driver only supports polled operation, in
order to make the code simpler, and since the interrupt processing
overhead is likely to slow down the throughput under Linux.Signed-off-by: Stephen Neuendorffer

This is an hvc-based virtio console driver. It's suboptimal becuase
hvc expects to have raw access to interrupts and virtio doesn't assume
that, so it currently polls.There are two solutions: expose hvc's "kick" interface, or wean off hvc.

Fix for the problem detected by Ingo Molnar:
enabling CONFIG_PCWATCHDOG=y crashes bzImage bootup.The reason for this can be found in drivers/makefile
We first do:
obj-y += char/
and later we do:
obj-y += base/ block/ misc/ mfd/ net/ media/So if we put a platform or isa or usb bus driver in char/watchdog
(which is called from the Makefile in drivers/char/Makefile)
then we didn't have the different device drivers initialized yet
(they are in drivers/base and drivers/usb and ...)This fix makes sure that we compile the watchdog drivers after
drivers/base, drivers/misc, drivers/pci and drivers/usb.
We also do the compile after hwmon because in the future the
watchdog temperature support will use the hwmon system.Signed-off-by: Wim Van Sebroeck

Add TTY input auditing, used to audit system administrator's actions. This is
required by various security standards such as DCID 6/3 and PCI to provide
non-repudiation of administrator's actions and to allow a review of past
actions if the administrator seems to overstep their duties or if the system
becomes misconfigured for unknown reasons. These requirements do not make it
necessary to audit TTY output as well.Compared to an user-space keylogger, this approach records TTY input using the
audit subsystem, correlated with other audit events, and it is completely
transparent to the user-space application (e.g. the console ioctls still
work).TTY input auditing works on a higher level than auditing all system calls
within the session, which would produce an overwhelming amount of mostly
useless audit events.Add an "audit_tty" attribute, inherited across fork (). Data read from TTYs
by process with the attribute is sent to the audit subsystem by the kernel.
The audit netlink interface is extended to allow modifying the audit_tty
attribute, and to allow sending explanatory audit events from user-space (for
example, a shell might send an event containing the final command, after the
interactive command-line editing and history expansion is performed, which
might be difficult to decipher from the TTY input alone).Because the "audit_tty" attribute is inherited across fork (), it would be set
e.g. for sshd restarted within an audited session. To prevent this, the
audit_tty attribute is cleared when a process with no open TTY file
descriptors (e.g. after daemon startup) opens a TTY.See https://www.redhat.com/archives/linux-audit/2007-June/msg00000.html for a
more detailed rationale document for an older version of this patch.[akpm@linux-foundation.org: build fix]

This patch series replaces the old non-generic Hardware Random Number
Generator support by a fully generic RNG API.This makes it possible to register additional RNGs from modules. With this
patch series applied, Laptops with a bcm43xx chip (PowerBook) have a HW RNG
available now.Additionally two new RNG drivers are added for the "ixp4xx" and "omap"
devices. (Written by Deepak Saxena). This patch series includes the old
patches by Deepak Saxena.The old x86-rng driver has beed split.
The userspace RNG daemon can later be updated to select the RNG through
/sys/class/misc/hw_random/ for convenience. For now it is sufficient to use
